- We have tested and compared our biochar residue with brands that charge 3x more, and Gardin's Biochar was significantly cleaner
- Great for your plants
- Makes the nutrients your plants need easier to access through an increase in soil biomass, microbial efficiency, and cation exchange (Lehmann, J et al. 2011)
- Increases plant productivity, especially in acidic soils (Saito, M. et al. 1990)
- Increases plant yields (Tian, Y et al. 2012)
- Increases surface area, allowing the plant to hold onto more nutrients, water, and microorganisms
- Increases natural disease resistance to mold, mildews, and broad mites (Elad et al. 2010)
- Great for our planet
- Helps sequester carbon from the environment
- Byproduct of industrial processes making it sustainable and waste reducing
How to Use
- Mix 1-3 cups of biochar directly into your soil/media.
- Activate new biochar by watering with a nutrient rich solution or compost tea.
- Check pH levels and adjust as needed*
*Biochar can have a liming effect on soils, be sure to keep your soil within the recommended pH for your plant.
